Results

Figure 1 The full line denotes the mean difference between two repeated measurements．The upper and lower dashed lines denote the limits of 95%consistency．

Figure 2 The maximum value within the consistency limits was 0．05 LogMAR and the minimum was-0．03 LogMAR．The upper limit of 95%consistency was 0．08 LogMAR， consistent with the general error range．（0．2 LogMAR），．indicating that these two visual charts have a high consistency．

Figure 3 The maximum value within the consistency limits was 0．04 LogMAR and the minimum was-0．05 LogMAR．The upper limit of 95%consistency was less than 0．2 LogMAR， indicating that these two charts have a high consistency．

Figure 4 The maximum value within consistency limits was 0．034 LogMAR and the minimum was-0．038 LogMAR． The upper limit of 95%consistency was less than 0．072 LogMAR，indicating that these two charts have a high consistency．

Discussion

Figure 5 The maximum value within consistency limits was 0．04 LogMAR and the minimum was-0．028 LogMAR． The upper limit of 95%consistency was less than 0．12 LogMAR，indicating that these two charts have a high consistency．
